Code:
<object classid="clsid:d27cdb6e-ae6d-11cf-96b8-444553540000" codebase="http://fpdownload.macromedia.com/pub/shockwave/cabs/flash/swflash.cab#version=8,0,0,0" width="800" height="600" id="como" align="middle">
<param name="allowScriptAccess" value="sameDomain" />
<param name="movie" value="como.swf" /><param name="quality" value="high" /><param name="bgcolor" value="#000000" /><embed src="index.swf" quality="high" bgcolor="#000000" width="800" height="600" name="como" align="middle" allowScriptAccess="sameDomain" type="application/x-shockwave-flash" pluginspage="http://www.macromedia.com/go/getflashplayer" />
</object>
That's the HTML code, I've bolded the part that might be wrong, the actual file is index.swf, and if I point IE at index.swf it works, so maybe the movie param tag is used by IE and it's looking for como.swf which doesn't exist?
Just my first guess without researching how to actually embed flash (I never use it either).
ETA: Meaning try changing the page so it says
Code:
<param name="movie" value="index.swf" />
